Evaluation Metrics. For InterHand2.6M [1]}, we report 3D Mean Per Joint Position Error (MPJPE). MPJPE is defined as the mean Euclidean distance between ground truth and predicted 3D joint locations, calculated after aligning the root joint for each left and right hand separately. The measurements are reported in millimeters (mm). For Tzionas dataset [2]}, we follow the common practice [1]}, [4]}, [5]} to use 2D end point error (EPE) for evaluation.
